| Re: heartworm preventative If you have mosquitoes then IMO, yur dog should be on heartworm preventative. The disease can kill and treatment is long and expensive.
Some people who live in areas with hard winter freezes take their dogs off meds over the winter and start again int he spring. However, often the test to verify that your dog is still negative before starting meds in the spring is more expensive than just keeping the dog on meds all winter. |
